Hopefully merging Tim's updates into my fork.

Hopefully this is the right approach to merge Tim's updates (from cursor hiding through Unity 4.3 controller mappings) into my fork (to allow updating my local version to pull those into SS).
Approach: Comparison of Arakade:master ... ouya:master then create pull request.  It's not obvious which repository this will get sent to so Tim, apologies if this appears in your inbox -- it was hoped to go the other way!
Here goes!
